Oh My Goddess! Vol 10

From the Dark Horse edition

Ever since a cosmic phone call brought the literal young goddess Belldandy into college student Keiichi's residence, his personal life has been turned upside down, sideways, and sometimes even into strange dimensions! It'll be one, two, three strikes you're out for the N.I.T. Softball Club if Keiichi can't help his sister win against their campus rivals - but with the goddesses stepping up to bat, it's not going to be the old ball game! Then, it's an unrelaxing hot springs vacation when Mara returns to challenge Urd to the most feared battle imaginable: karaoke! Plus: four pages of color, ten Mini-Goddess strips, a message from creator Kosuke Fujishima, and your fan art and letters!
